Aab Analog Output Range; Lrv Physical Lower Limit - Siemens TXP-CLC Manual

Explanation
The CAO block can be parameterized to provide an analog output signal on the
SIM I/O module that responds to a control scheme. Below is the parameter mask
for the CAO function block followed by a brief explanation of each output and
parameter:
Outputs
KSIM
Binary Output value of "1" indicates that the signal is simulated and not from the
process. The output simulation is set from the ES680 similar to the FB70 BT
block in chapter 7. This simulation can be used as an output from the CAO block
for other logic.
Parameters

AAB Analog Output Range

Defines whether 0 to 20 mA or 4 to 20 mA signals are to be output to the SIM I/O
module.
Range of values: 0 to 2
Meaning: 0 = irrelevant (configured spare)
1 = output 0 to 20 mA
2 = output 4 to 20 mA
Default setting: 2

LRV Physical Lower Limit

Describes the lower range value of the corresponding physical variable range
Range of values: 0 to 10,000
Meaning: Starting value for correlating the process value to the selected
output range
Basic setting: 0
